As I mentioned, unless you logged the CREATE DATABASE statement I don't think the creation date is stored anywhere, but you could look at the modification times of the oldest files in the database's directory. For example, one of my databases is named test. I can find that database's oid by querying pg_database: test=> SELECT oid FROM pg_database WHERE datname = 'test'; oid ------- 16388 (1 row) I then list the files in that database's directory, sorted by time: % ls -lt $PGDATA/base/16388 | tail -2 -rw------- 1 postgres postgres 4 Dec 6 09:39 PG_VERSION -rw------- 1 postgres postgres 0 Dec 6 09:39 1248
